I had same problem at 4.7ghz 1.3v.
Set load line callibration to the ultra or extreme will solve the problem,
did for me. Keeps voltage at what you set 1.3v, not some bull****
fluctuation between 1.26 and 1.31 without.

Thinking about getting a refund on my MSI P67A-GD65 and switching to a P8P67 Deluxe. Have folks tried their CPUs on different boards and been able to achieve the same overclocks with lower voltage (or conversely, higher overclocks on the same voltage)?

With the MSI, I feel like I have to make compromises when I upgrade the BIOS- get bug fixes and updates, but lose present overclock capability. Had to up my voltage 0.05 just to stay stable at 4.6. Also, my voltage is almost never what I set it at, despite what vdroop (LLC) is set at- If I set 1.425 in bios, it idles at 1.40, and at load it'll jump to 1.456 (according to CPU-Z).

Also, when testing your overclocks for stability, if it's benchmark/torture test/folding stable, but then BSODs on something trivial like opening the start menu, loading a youtube video, or something- would you automatically increase voltage or consider something else?

I can run any stability test for several hours, not a hiccup, but I get at least 1-0000000124 BSOD dump every day while surfing, or on youtube, or even at idle, even with my ram at stock settings, is anyone else having this problem ?

These boards seem to be really picky about voltage... I remember on 775 I could boot pretty much every time unless I was doing something that I knew was impossible (like 4GHz at 1.3v etc.)

But now with this setup I can be at like 1.39v in the BIOS and it won't boot at all... then I can do 1.4v in the BIOS and its completely stable. I would think with the lower of the two voltages it would at least boot then BSOD when I am running prime or something.

I dont use offset because I leave c states on auto , which with 1305 = disabled, so my clocks are always 4.5, if I put voltage on auto it jumps to about 1.38. I have noticed no matter what, the voltage spikes from 1.312 to 1.344 all day long my settings are
